OPINION
Opinion by
This consolidated appeal involves the alleged sexual assault of a patient by nursing staff in a hospital intensive care unit (ICU). 1 Appellants Christus Spohn Health System Corporation d/b/a Christus Spohn Hospital Corpus Christi-Shoreline *872 (Spohn-Shoreline), Edwin DeJesus, and Alain Njoh challenge the trial court’s denial of their motions to dismiss a lawsuit filed by appellees Sandra Sanchez and Omar Aleman for failure to serve an adequate expert report as required by section 74.351. See Tex. Civ. Prac. & Rem.Code Ann. § 74.351(a)-(b) (Vernon Supp. 2009). By three issues on appeal, appellants argue that: (1) appellees’ claims are health care liability claims; (2) appellees’ expert reports did not constitute a good-faith effort to comply with the statute and were fatally deficient; and (3) section 74.351’s expert report requirement is constitutional under the United States and Texas Constitutions. We affirm.
I. BACKGROUND
In October 2007, Sanchez underwent spinal fusion surgery at Spohn-Shoreline. She was recovering in the ICU when she alleges that Njoh and DeJesus, a registered nurse and a certified nurse’s assistant, entered her room and made unwanted sexual advances toward her. Sanchez alleges that one of the men undressed her and exposed her body for the other to see. She claims that they turned her over using their hands instead of a turning pad and, while they were moving her from the bed to a chair in her room, they danced with her. Sanchez alleges that during these physical contacts, Njоh and DeJesus were making sexual overtures and comments and that the improper conduct continued until she was discharged from the hospital a few days later.
In February 2008, appellees sued Spohn-Shoreline for negligent hiring, supervision, training, and retention of its employees and vicarious liability for the conduct of Njoh and DeJesus. Appellees timely served the expert report and curriculum vitae of Laura Burchell-Henson, a registered nurse. 2 Tex. Civ. Prac. & Rem. Code Ann. § 74.351(a). Spohn-Shorеline filed objections to the report and a motion to dismiss appellees’ lawsuit on the basis that their expert report did not constitute a good-faith effort to comply with the requirements of the statute. Appellees responded to the motion, arguing that their claims were not health care liability claims subject to section 74.351 and that the expert report requirement was unconstitutional under the United States and Texas Constitutions. In August 2008, appellees amended their petition to add causes of action against DeJesus and Njoh, in their individual capacities, for assault and intentional infliction of emotional distress. After the trial court granted appellees an extension of time to amend then* expert report, appellees filed a report by George S. Glass, M.D. Spohn-Shoreline filed objections to the second report and all appellants filed motions to dismiss the suit for failure to file an adequate expert reрort. The trial court denied both motions to dismiss, and these appeals ensued. See Tex. Civ. Prac. & Rem.Code Ann. § 51.014(a)(9) (Vernon 2008) (authorizing an interlocutory appeal of the denial of a motion to dismiss filed under section 74.351(b)).
II. DISCUSSION
A. Health Care Liability Claims
By the first issue, appellants assert that appellees’ claims are health care liability claims governed by chapter 74 of the civil practice and remedies code. Specifically, appellants argue that the underlying nature of appellees’ clаims is that appellants *873 breached the standards of care and safety owed to Sanchez. With regard to appel-lees’ claims against Spohn-Shoreline, we agree. However, we cannot so conclude with respect to appellees’ claims against Njoh and DeJesus in them individual capacities.
1. Standard of Review and Applicable Law
“[W]hether a claim is a health care liability claim pursuant to section 74.351 is a question of law and is reviewed de novo.”
Valley Baptist Med. Ctr. v. Stradley,
[A] cause of action against a health care provider ... for treatment, lack of treatment, or other claimed departure from accepted standards of medical care, or health care, or safety or professional or administrative services directly related to health care, which proximately results in injury to or death of a claimant, whether the claimant’s claim or cause of action sounds in tort or contract.
Tex. Civ. Prac. & Rem.Code Ann. § 74.001(a)(13) (Vernon 2005).

“A cause of action alleges a departure from accepted standards of medical care or health care if the act or omission complained of is an inseparable part of the rendition of medical services.”
Diversicare Gen. Partner, Inc. v. Rubio,
In determining whether appel-lees’ claims are indeed health care liability claims, we focus on the “gravamen,” or underlying nature, of the claim.
Id.
“[W]e are not bound by the form of the pleading,” and the nature of the claim is not determined simply by the status of the defendant or the place of injury.
Id.; see Marks,
2. Claims against Njoh and DeJesus
Njoh and DeJesus argue that appellees’ claims against them for assault and intentional infliction of emotional distress actually center on their rendering of health care services to Sanchez. They contend that Sanchez’s allegations — that they undressed her so they could view her naked body, moved her with their hands instead of a turning pad, and dаnced with her while they were moving her from the bed to a chair — are all subjective interpretations of what, in reality, were specific tasks routinely performed by nursing staff, i.e. changing her clothes in preparation for the doctor, turning her over in her bed, and helping her to the chair in her room. Njoh and DeJesus argue that Sanchez’s differing perception of the conduct does not take her claims outside the confines of the health care liability statute. We disagreе.
*874
Although we acknowledge that the previously described tasks may be part and parcel of the care given to hospital patients by nursing staff, we do not view the conduct challenged by appellees in isolation from the surrounding circumstances, as do Njoh and DeJesus. Because in addition to describing the undressing, turning over, and moving of Sanchez, appellees also allege that Njoh and DeJesus made sexual overtures toward Sanchez in the process of pеrforming these tasks. Appel-lees claim that Njoh and DeJesus commented to Sanchez about her body while they were undressing her and allegedly danced with her and, at one point, even tried to climb in the bed with her. Appel-lees further allege that one of the two wrote “I love you” on the white board in Sanchez’s room. We would be remiss to conclude that such conduct was related to the health care being provided to Sanchez or somehow involved the professional judgment of Njoh and DeJesus.
See Jones v. Khorsandi,
Appellees’ amended petition alleges causes of action against Njoh and DeJesus for assault and intentional infliction of emotion distress, and we conclude that the underlying nature of appellees’ claims, indeed, rests squarely in these intentional actions that had “nothing to do with a health care provider’s lapse in professional judgment or failure to protect a patient due to an absence of supervision or monitoring.”
Holguin v. Laredo Reg’l Med. Ctr., L.P.,
3. Claims against Spohn-Shoreline
Similarly, Spohn-Shoreline contends that the underlying nature of appel-lees’ claims is that it did not care for Sanchez within the accepted standards of care and safety. However, unlike appel-lees’ claims against Njoh and DeJesus, aрpellees’ claims against Spohn-Shoreline are based on negligence, implicate the standards of care and safety contemplated by chapter 74, and directly relate to its rendering of health care to Sanchez.
See
Tex. Civ. Prac. & Rem.Code Ann. § 74.001(a)(13);
see also Stradley,
Decisions regarding the protection of patients and the supervision and monitoring of staff involve professional judgment,
see Diversicare,
Appellees respond that their claim against Spohn-Shoreline for vicarious liability, in particular, is not a health care liability claim subject to the expert report requirement. However, Texas courts have clearly held that a plaintiff cannot circumvent the expert report requirement by artfully pleading her health care liability claim based upon the negligence of the health care provider as some other cause of action, such as vicarious liability.
See Garland Cmty. Hosp. v. Rose,
We conclude that the “gravamen” of ap-pellees’ claims is that Spohn-Shoreline breached the standards of care and safety owed to Sanchez by failing to protect her from the allegedly assaultive conduct of its nursing staff.
See Marks,
B. Expert Reports
In the second issue, Spohn-Shoreline argues that appellees’ expert reports were fatally deficient. 5
*876 1. Standard of Review and Applicable Law
We review a trial court’s decision on a motion to dismiss under section 74.351 of the civil practice and remedies code for abuse of discretion.
Jernigan v. Langley,
Under section 74.351 of the Texas Civil Practice and Remedies Code, a claimant must “serve on each party or the party’s attorney” an expert report and curriculum vitae “not later than the 120th day after the date the original petition was filed.” See Tex. Civ. Prac. & Rem.Code Ann. § 74.351(a). An expert report is “a written report by an expert that provides a fair summary of the expert’s opinions ... regarding applicable standards of care, the manner in which the care rendered ... failed to meet the standards, and the causal relationship between that failure and the injury, harm, or damages claimed.” Id. § 74.351(r)(6).
In our review of the expert report, we are limited to the four corners of the report in determining whether the report manifests a good-faith effort to comply with the statutory definition of an expert report.
Palacios,
2. Analysis
Spohn-Shoreline first argues that Nurse Burchell-Henson’s report did not adequately set forth the standard of care and/or safety and breach because the report is eonclusory, speculative, and does not differentiate between the standards of care applicable to Spohn-Shoreline as opposed to the individual defendants.
See Taylor,
Nurse Burchell-Henson’s report states that the “standard of care requires that the hospital and its nursing staff provide adequate supervision to their certified nursing assistants and licensed nursing personnel.” The report further states that the “standard of care requires that the hospital and its nursing staff protect their patients from sexual harassment and abuse.” It is clear to this Court that, although she references the “nursing staff’ in these articulated standards of care, Nurse Burchell-Henson is describing the duties owed by Spohn-Shoreline to its patients.
See Univ. of Tex. Sw. Med. Ctr. v. Dale,
Moreover, we conclude that Nurse Burc-hell-Henson identified the care that was expected but not rendered under the applicable standard of care. She states that Spohn-Shoreline “[flailed to provide adequate supervision to the CNA [DeJesus] and the RN [Njoh],” “[flailed to protect Ms. Sanchez from sexual harassment and sexual abuse,” and “[flailed to provide safety to Ms. Sanchez in her immediate post operative [sic] when the CNA lifted Ms. Sanchez up and began dancing with her.” She explains the specific tasks and responsibilities required of Spohn-Shore-line and notes that it failed to perform as such. In short, the report put Spohn-Shoreline on notice of the specific complained-of conduct, and we cannot say that the trial court abused its discretion in finding that the report sufficiently set forth the standard of care and breach.
See Pa-lacios,
Spohn-Shoreline next complains that the report of Dr. Glass did not establish the causation element required under the statute.
See Bowie Mem’l Hosp. v. Wright,
In his report, Dr. Glass opines at length about the alleged conduct of Njoh and Dejesus and describes the depression, severe anxiety, panic, nightmares, and social isolation that Sanchez suffered following her stay at Spohn-Shoreline. Dr. Glass observes that Sanchez was “unable to care [sic] and protect herself [sic] felt vulnerable, harassed by the people who were supposed to be caring for her in the hospital ICU.” He then concludes that: “The fact that [Sanchez] was vulnerable, unable to protect herself, and felt as if her person was violated has caused her to now have symptoms of Major Depression and Post Traumatic Stress Disorder.”
Dr. Glass’s emphasis on Sanchez’s vulnerable condition, in particular, puts Spohn-Shoreline on notice of the conditions called into question by appellees’ claims.
See Palacios,
Based on the foregoing, we conclude that the expert reports of Nurse Burchell-Henson and Dr. Glass adequately set forth the standard of care, identified how Spohn-Shoreline breached the standard, and explained how the breach causеd the injuries claimed by appellees.
See Palac-ios,
III. CONCLUSION
The orders of the trial court denying appellants’ motions to dismiss are affirmed.
Notes
. This opinion consolidates the Court’s analysis of both appeаls. See Tex.R.App. P. 47.1.
. Appellees maintain that their claims are not health care liability claims and that they served an expert report in an "abundance of caution” to preserve dreir rights to proceed with the lawsuit.
. The statute's definition of health care provider includes hospitals, registered nurses, and employees acting in the course and scope of their employment with the health care provider. See Tex Civ. Prac. & Rem.Code Ann. § 74.00l(a)(l 1)(G), (12)(A)(i), (I2)(B)(ii) (Vernon 2005).
. Having decided that аppellees' claims against Njoh and DeJesus are not health care liability claims, we need not reach Njoh and Dejesus’s contentions regarding the adequacy of appellees’ expert reports or concerning the constitutionality of the expert report requirement. See Tex R.App P. 47.1.
. By a sub-issue, Spohn-Shoreline complains that the trial court erred in granting appel-lees' request for a thirty-day extension to amend the report of Nurse Burchell-Henson. Spohn-Shоreline argues that because the only expert report served by appellees within the 120-day deadline was authored by a nurse who, under the express terms of the statute,
*876
cannot offer an opinion regarding causation, appellees effectively failed to serve any expert report on Spohn-Slioreline within the time frame required by section 74.351.
See
Tex. Civ Prac. & Rem.Code Ann. § 74.351(c) ("If an expert report has not been served within the period specified ... because еlements of the report are found deficient, the court may grant one thirty-day extension to the claimant in order to cure the deficiency.”). In other words, Spohn-Shoreline argues that the report by Nurse Burchell-Henson was not merely deficient but, rather, no report at all and that, even if they were entitled to a thirty-day extension, appellees could use the extension only to amend the Burchell-Henson report, not to file a new report by a separate expert. However, the Texas Supreme Court has held that objections to a nurse's qualifications to act as an expert in a health care liability claim go to the sufficiency of the report and not to its existence.
Ogletree v. Matthews,
. Having concluded that appellees' expert reports met the requirements of section 74.351 and that the trial court did not err in denying Spohn-Shoreline’s motion to dismiss, we need not reach its third issue regarding appel-lees' argument that the expert report requirement is unconstitutional. See Tex.R.App. P. 47.1.
